MR images show hyperintense lesions in the left basal ganglia. Numerous hyperintense lesions also are seen around the gray matter-white matter junctions, findings indicative of a hematogenously disseminated process.
Diffusion-weighted MR image shows high-signal-intensity rims and low-signal-intensity centers of the lesions.
Unenhanced T1-weighted MR image shows hyperintense borders, a somewhat irregular and “shaggy” appearance, and low-signal-intensity centers of the lesions
